One root of equation 3x 2 - mx + 4 = 0 is 1, the value of m is : 1. 7 2. -7 3. 4/3 4. -4/3

Since, 1 is the root of equation 3x 2 - mx + 4 = 0. ∴ x = 1, will satisfy the equation 3x 2 - mx + 4 = 0. ⇒ 3(1) 2 - m(1) + 4 = 0 ⇒ 3 - m + 4 = 0 ⇒ 7 - m = 0 ⇒ m = 7. Hence, Option 1 is the correct option.

Answer

Since, 1 is the root of equation 3x² - mx + 4 = 0.

∴ x = 1, will satisfy the equation 3x² - mx + 4 = 0.

⇒ 3(1)² - m(1) + 4 = 0

⇒ 3 - m + 4 = 0

⇒ 7 - m = 0

⇒ m = 7.

Hence, Option 1 is the correct option.
